Google has put quite an effort into documenting how to take care of multiple screen sizes - check http://developer.android.com/guide/practices/screens_support...

I am not sure how it helps to game developers but it is pretty concise guide for general app development.

We have gone through the screen size adjustments and minor incompatibilites across versions when porting to Galaxy Tab (I have summarized the experience in the blog: http://touchqode.com/blog/008_developing_for_galaxy_tab.htm ) and then when Honeycomb came out.

But more often than not it is our hackiness or vendor fancy tweaks that cause problems rather than the android itself.
